The graphics for
Puzz 3D: Bavarian Castle are the same quality as in
Victorian Mansion, although there’s a lot more gray. In
Victorian Mansion’s case, the primary color was red. The graphics are detailed 2D in the building modes, relatively high-quality 3D construction mode, and absolutely atrocious 3D “look-around” mode. The FMVs throughout the game are low-budget and cheesy with bad backgrounds, but they’re passable to move along the mediocre plot of the game.
The sound is forgettable, with rather generic sound effects and music. You’ll tune it out, though, as you work on the puzzle.
